In the late 1940's a similar problem occurred in the work of three sociologists, working in three countries, on three similar sets of data. Natalie Rogoff, David Glass and G6sta Carlsson all faced the problem of making sense of data on intergenerational occupational mobility. A matrix of frequencies of occupations of respondents by occupations of fathers could be converted, in an obvious and straightforward fashion, into matrices of inflow and outflow percentages. Their joint problem arose in comparing inflow percentages across rows or outflow percentages across columns. The problem was that, as sociologists, concerned with the extent that origins in socially meaningful categories influenced destinations in the same socially meaningful categories, they were stuck with occupational categories that differed from one another dramatically in size. A secondary (though hardly trivial) problem was the fact that, in all their data, the two marginal distributions, the respondents' generation and the fathers' ‘generation’, were notably dissimilar — a consequence of both differential fertility and a general upward shift in the occupational distributions of the three countries. All sought a technique that would ‘make the two time periods comparable with respect to occupational structure’.  相似文献

Purpose: Exercise is important for the prevention of osteoporosis and the reduction of fracture risk because it improves muscle mass and strength, besides improving balance. We evaluated the effect of a specific exercise program on bone mass and quality and physical function capacity in postmenopausal women with low bone mineral density. Methods: Participants (N = 125) underwent a bone mass (Dual X-ray Absorptiometry), bone quality (osteosonography), and physical functional capacity assessment. Fifty-eight of them took part in an 11-month exercise program (E), that included a multicomponent (strength, aerobic capacity, balance, joint mobility) dual-modality (on ground and in the water; alternating group and home-based exercise periods) exercise regimen. The others represented a control group (C) that did not exercise. After the exercise program all participants were reevaluated. Results: After the training program: femoral neck T-score significantly improved in E; C significantly decreased all bone quality (osteosonography) parameters, whereas E showed no differences; E significantly improved all the physical function capacity parameters, while most of them decreased or did not change in C. Conclusions: A specific exercise program targeting osteoporosis improves physical function capacity, reduces physiological bone loss, and maintains bone quality in low bone mineral density postmenopausal women.  相似文献

abstract

The present study intended to determine how the socioeconomic status (SES) of citizens and public health communications help explain citizens’ risk perception and actions taken during Zika virus outbreaks in 2016. We used data from a nationally representative study conducted in March 2016 by the Associated Press–National Opinion Research Center to analyze 831 American adult responses regarding Zika. We found that respondent risk perception and actions taken diminished as SES level rose. Risk perception was also found to mediate preventive actions’ associations. To quell the global spread of emerging infectious diseases (EIDs) like Zika, health organizations worldwide must understand how SES contributes to Zika (and other future EIDs) risk perception and preventive action. A more compelling form of public health communications must be developed that takes into account the impact made on future outbreaks and infections by these higher-SES “risk assessments.”  相似文献

Abstract

Objectives: This article presents a new approach to intervention for eating disorders and body image concerns on college campuses, using a model of integrated eating disorder screening and intervention. Formative data on implementation feasibility are presented. Participants: College students enrolled at 2 universities between 2011 and 2012. Methods: The Healthy Body Image program is an evidence-based screening and intervention platform, enacted via community and online resources. An online screen was used to identify students at varying levels of risk or eating disorder symptom status; responses were used to direct students to universal or targeted online interventions or further evaluation. Universal prevention programs to improve healthy weight regulation and body image culture were offered to all students. Results: Formative data from 1,551 students illustrates the application of this model. Conclusions: The Healthy Body Image program is feasible to deliver and provides a comprehensive system of screening, evidence-based intervention, and community culture change.  相似文献

ABSTRACT

Many college students today are no longer using the terms straight, gay, lesbian, bisexual, or transgender to self-identify their sexual orientation or gender identity. This commentary explores research related to fluidity of sexual identities, emerging sexual identities used by college students, and how these identities interact with the health and well-being of the student. Additionally, the authors discuss strategies to help college health professionals provide a sensitive environment and clinical experience for students whose sexual identity is fluid.  相似文献

A study was conducted to assess change in numbers, expenditures, and case mix of nursing home residents as Medicaid investment in home- and community-based services (HCBS) 1915(c) waivers increased in seven states. The seven states provided Medicaid expenditure and utilization data from 2001 to 2005, including waiver and state plan utilization. The Minimum Data Set was used for nursing home residents. For three states, community assessment data were also used. In six states, the number of nursing home clients decreased as the numbers of HCBS clients grew. However, in most states, the number of additional waiver clients often greatly exceeded reductions in nursing home residents. Nursing home payments decreased moderately, but this decrease was offset by increases in HCBS waiver and state plan expenditures, leading to a net increase in long-term support services (LTSS) expenditures from 2001 to 2005. Increases in waiver expenditures outpaced increases in waiver clients, indicating expansion of services on top of expansion in clients. States that showed substantial increases in HCBS showed only modest increases in nursing home case mix. The case mix for nursing home residents was more acute than that for HCBS users. The expectation that greater HCBS use would siphon off less severe LTSS users and hence lead to a higher case mix in nursing homes was partially met. The more acute case mix in nursing homes suggests that HCBS serves some individuals who were previously cared for in nursing homes but many who were not. Efforts to promote substitution of HCBS for institutional care will require more proactive strategies such as diversion.  相似文献

Domestic labor researchers have examined a multitude of duties disproportionately performed by women, yet the responsibility associated with navigating a couple's fertility—fertility work—has been overlooked. Using data from the 2006–2010 National Survey of Family Growth (N = 1,415), the author examined how racial and socioeconomic factors affect the division of contraceptive fertility work among married and cohabiting women who rely on either their partners' vasectomies or their own sterilizations. Drawing theoretical connections between fertility work and housework, resource‐ and gender‐based perspectives were used to assess whether women's or their partners' characteristics are stronger predictors of sterilization type, and whether women's absolute or relative education level has a greater impact. Findings suggest that White and socioeconomically privileged women are more likely to have vasectomized partners than disadvantaged women. Male partners' characteristics were more closely associated with sterilization type than women's characteristics, lending greater support for the gender‐based hypotheses.  相似文献

ABSTRACT

Programs or policies that are effective in reducing social problems have several things in common: They acknowledge the realities of culture, respect the sociocultural underpinnings of the community, and are often built on an innovative understanding of the issues. Policies that are created without regard for the culture in which they are to operate are destined to fail. This study discusses cultural attributes of different motivations, benefits, and approaches to breast-feeding, depending on the development of their infrastructure, scientific understanding, reliance on myths to understand their environment, and social norms. It argues that in some cases ignorance and lack of scientific information result in policies (both formal and informal) that negatively impact breast-feeding, whereas in other cases cultural or social norms drive policy decisions. Three examples of policies that impact breast-feeding negatively are discussed in this article. Two of them relate to developing nations and the third occurred in the United States, although it could also occur anywhere people lack basic information about the impact of hormones on normal human physiology and human sexual response.  相似文献
